Table 2. The 95% credibility intervals of trophic contribution (%) of organic matter sources or prey groups to the diet of the consumer groups.

Consumers		Habitat	Organic matter source				Prey groups
Cluster/Main trophic groups			CPOM	FPOM	SOM	MPB	Inter-/subtidal pelagic-affinity prey (A)	Subtidal benthic-affinity prey (C1)	Intertidal benthic prey (D)

The codes of cluster group of consumers are given in Table 1 and Fig 7. CPOM, FPOM, SOM and MPB stand for coarse, fine suspended particulate organic matter, sedimentary organic matter and microphytobenthos, respectively.
